Diopter-corrected tooth-shaped mosaic planar waveguide optics

Abstract

The invention provides a tooth-shaped embedding planar waveguide optical device which has a diopter correction function and can be used for full-eye wearing displaying. The tooth-shaped embedding planar waveguide optical device comprises a display light source, a collimation lens, a coupling input surface, a planar waveguide substrate, a micro tooth-shaped structure and a thin negative lens, wherein the display light source is used for sending displaying light waves for displaying a required image; the collimation lens is used for collimating the light waves sent by the light source; the coupling input surface is used for coupling the collimated light waves to a planar waveguide; the planar waveguide substrate carries out reflection transmission on the coupled light waves to form total-reflection light waves; the micro tooth-shaped structure is used for carrying out coupling output on the total-reflection light waves; the thin negative lens is used for correcting the diopter. The tooth-shaped embedding planar waveguide optical device has the characteristics of convenience in diopter correction, light weight, compact structure, simple processing technology, flexible visual field adding and high light wave coupling efficiency, and can be either used for wearable displaying or the application field of naked-eye 3D displaying of a medical ear mirror, GPS navigation, mobile screen displaying and the like.

Description

technical field [0001] The invention relates to a planar waveguide optical device, in particular to a tooth-shaped inlaid planar waveguide optical device with diopter correction that can be used for full-eye wearable display. Background technique [0002] The traditional helmet-mounted display is realized by a 45° reflective structure. This structure has a great contradiction between the increase of the field of view and the overall weight of the helmet. In order to increase the field of view, it can only be achieved by increasing the area of ​​the 45° reflective surface, which means that the weight of the overall reflective system increases. Usually, the helmet-mounted display device uses optical components to virtually display image information at a certain distance in front of the human eye in order to facilitate the wearer to browse information without affecting the normal behavior. The core component of this type of optical display system consists of three parts: grap...
